bPIPE-CUTTER. l

SPECIFICATION forming part of Letters Patent No. 252,749, dated January 24, 1882.

Application filed October 13,1881. (No model.) I

To all whom 'it may concern Be it known that l, CHARLES FENTON, a citizen of the United States, residing at New York, in the county of NewYork and State ot" New York, have invented new and usef'ul Improvements in Pipe-Gutters, of which the following is a specilication.

The object of this invention is to facilitate the removal of the movable cutter jaw andthe interchanging of the ditl'erent styles of the cutters employed in a pipe ,cutter or wrench, and also to improve the general construction of the device, as hereinafter fully described, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the pipecutter with a portion ofthe casing broken away. Fig. 2 is a perspective view ofthe movable cutter-jaw detached. Fig is a plan view thereof. Fig. 4 is a-longitudinul section taken through the nut and operating-rod. Fig. 5 shows the uut detached. Fig. o represents two forms ct cutter.

The stock A and the stationary overhan-giug 2 5 jawB of my improved pipe cutter or wrench are preferably cast in one piece, the angularface of the latter being hardened by any approved process. The stock comprises au oblong rectangular casing, a, within which themovahle block or jaw C, that carries the cutter, is arranged to slide. This movable jaw is formed with a rectangular mortise,.c, at its forward end to receive a cutter consisting ot' the block E, of tempered steel, having a rectangular shank, e, adapted to t in the mortise of the said jaw, the segmental or concave cutting-edge e', and shoulders e2 e2, which abut against the face of thcjaw when the cutter is in place, and serve to hold the same trulyin position and tak-e the strain ofi' the pivot or pin F, by which the cuttcr is held in place, and which passes through the 'mortised end of the jaw and through an,

aperture in the shank of the cutter. This form l"ot cutter can, however, be removed and replaced by the cutter-disk G, such change being e'ected by withdrawing the pin from the shank ofthe cutter, and, after substituting the cutterdisk therefor, passing the pin through the jaw .and the central perforation of the last-meritioned cutter. The construction of t-he remaining portions of the device has special reference to the facilitating of this interchange ofcutters. To this end the operating-rod H, which is ein, ployed for the purpose of causing the cutterjaw to slide back and forth within the casing,

Aand which is provided with the usual handle outer portion of the T-shaped mortise beingl received in the annular recess ot' the rod, and

the annular shoulder It at the end of the rod being received in the inner and vwider portion ofthe said mortise within the cutter-jaw. This mortise of the cutter-jaw is formed from side to side thereof, whereby, when the rod and the jaw areremoved from the stock, the detachinentof the said two members can be readily effected. It will be observed that by this construction of parts a simple and effective con- -nection between the rod and the jaw is effected without the aid of a locking-key, the rod can be turned freely in the. mortise of the cutterjaw, and the operating-rod also subserves as a handle, by means of which the instrument is manipulated around a pipe to cut the same.-

To provide a screw-threaded hearin g for the operating-rod, I forni a block or nut, K, with a screw-threaded bore, within which the screwthreaded portion of the operating-rod is arranged to work.

The casing within which the cutter-jaw works is formed with recesses a through two opposite sides at its outer end, and the nut is formed with a rectangular shank, k, which tits within the recessed end of the casing. 1t is held in this position by means of pins L L, passing through its shank andthe casing, and it is f'urther provided with shoulders 7c', that it against the outer end ofthe casing, thereby materially strengthening the connection between the said parts.

When it is desired to interchange cutters it will only be necessary to withdraw the pins L and then withdraw the nut, the operating-rod,

andthe cutter-jaw from the casing, after which the cutter can be introduced in the manner before described.

What I claim is The combination of the casing provided with an overhangiug stationary jaw, the nut having In testimony WhereofI have hereunto set my a threaded bore and ashank arranged within hand in the presence of two subscr hing Witth'e lower end of the casing, the transverse remesses.

movable pins extending through the easing and 5 shank of the nut, the movable block arranged CHARLES FENTON.
